• [8i] how to calculate a moving average?

  I am trying to calculate a moving average over a specific period of time, but I can't quite figure out how to do this. For this particular problem, I am also stuck on a 8i database.
  
  Some examples of data for the problem:

  CREATE TABLE     my_data
  (     order_no     CHAR(10)
  ,     seq_nbr          CHAR(4)
  ,     area_id          CHAR(4)
  ,     start_date     DATE
  ,     unit_time     NUMBER(7,2)
  );
  
  INSERT INTO my_data VALUES ('0000567890','0010','A001',TO_DATE('05/01/2000','mm/dd/yyyy'),0.34);

  INSERT INTO my_data VALUES ('0000123456','0010','A001',TO_DATE('04/01/2001','mm/dd/yyyy'),0.39);
  INSERT INTO my_data VALUES ('0000123456','0020','A001',TO_DATE('04/02/2001','mm/dd/yyyy'),0.98);
  INSERT INTO my_data VALUES ('0000123456','0030','A002',TO_DATE('04/03/2001','mm/dd/yyyy'),0.77);
  INSERT INTO my_data VALUES ('0000123456','0040','A003',TO_DATE('04/03/2001','mm/dd/yyyy'),0.28);
  INSERT INTO my_data VALUES ('0000123123','0010','A001',TO_DATE('12/01/2001','mm/dd/yyyy'),0.31);
  INSERT INTO my_data VALUES ('0000123123','0020','A001',TO_DATE('12/02/2001','mm/dd/yyyy'),0.86);

  INSERT INTO my_data VALUES ('0000111111','0020','A001',TO_DATE('06/02/2002','mm/dd/yyyy'),0.84);
  INSERT INTO my_data VALUES ('0000111111','0030','A002',TO_DATE('06/03/2002','mm/dd/yyyy'),0.78);
  INSERT INTO my_data VALUES ('0000111111','0040','A003',TO_DATE('06/03/2002','mm/dd/yyyy'),0.26);

  It is a sample of the actual data, which includes the lines around 50K, and is the result of a query, not a table. In addition, the actual data also have a reference number attached to each order, and the end result will be be partitioned by party id number and the region. This sample represents basically something, you might see a unique part number. In addition, these records at the time spacing is not predictable. You might have a single year that has 20 ordered, and another year (or years) that does not.
  
  Here is where I am now in the problem. For example, suppose I want to calculate a moving average over 2 years (average for the 2 years preceding the date of the current row). For my actual data, I probably want to be able to change the period of time (at different times in several queries) on which the moving average is calculated.
  
  I thought that using the analytical function AVERAGE with a window clause might be the way to go, but I don't know exactly how to use the window clause. I can even be completely wrong interpret what is its use, but if all goes well, it should still show what I'm after.
  

  SELECT     area_id
  ,     AVG(tot_area_unit_hrs)     
       OVER     (
            PARTITION BY     area_id
            ORDER BY     min_start
            ROWS          BETWEEN     --2 years prior to min_start of current row
                      AND     CURRENT ROW
            )
  ,     --something to indicate the time period the average is over     AS time_period
  FROM     (
       SELECT     order_no
       ,     area_id
       ,     MIN(start_date)     AS min_start
       ,     SUM(unit_time)     AS tot_area_unit_hrs
       FROM     my_data
       GROUP BY     order_no
       ,          area_id
       )
  ORDER BY     area_id
  ,          time_period

  As you can see from the above query, I want to calculate the sum of the unit_time for each order/area_id combo, then roll the way to this total time. (I'm the average total time that a product passes through each area_id per order).
  
  I want to see results like something along those lines... I really don't like how the time period is identified, as long as I can pay by him in chronological order, and he tells me what period of time it covers. The way I show with period_start and period_end in the results of the sample below is just a way that I thought to do this.
  

  area_id   period_start period_end   avg_unit_time   
  ----------------------------------------------------
  A001      4/30/1998    5/1/2000     1.120           
  A001      3/31/1999    4/1/2001     1.245           
  A001      11/30/1999   12/1/2001    1.220           
  A001      5/31/2000    6/1/2002     1.223           
  A001      4/30/2001    5/1/2003     1.153           
  A002      5/2/1998     5/3/2000     0.910

  Any suggestions?

  Hello

  You're close enough. You want a window based on the BEACH, no LINES.
  LINES BETWEEN... means that you know exactly how many lines will be in the window, and you don't care what range of values that represents.
  RANGE BETWEEN... means that you know the exact scope of the ORDER BY value to include in the window, which could mean any number of lines.

  When you say "RANGE BETWEEN x BEFORE...". "where the words ORDER BY id of a DATE, x is considered as the number of days. (Which is consistent with the arithmetic DATE Oracle).

  Try this:

  SELECT     area_id
  ,     min_start - 730          AS period_start
  ,     min_start             AS period_end
  ,     AVG(tot_area_unit_hrs)
       OVER     (
            PARTITION BY     area_id
            ORDER BY     min_start
            RANGE BETWEEN     365 * 2     PRECEDING
                  AND     CURRENT ROW
            )               AS avg_unit_time
  FROM     (
       SELECT     order_no
       ,     area_id
       ,     MIN(start_date)     AS min_start
       ,     SUM(unit_time)     AS tot_area_unit_hrs
       FROM     my_data
       GROUP BY     order_no
       ,          area_id
       )
  ORDER BY     area_id
  ,          period_end
  ;
  

  Output of your sample data:

  The period_starts are not quite what you posted, but, if I understand you correctly, you don't mind that.
  There should be no problem of partitioning an additional column.

  my phone asking me always Apple ID password of the account that I did not create. I have this account in my settings, but I don't know how to remove it. Thanks for the reply.

  There are several places an identifier Apple is used on an iPhone.

  • If it's the Apple of a former owner of the phone ID, and it is in settings/iCloud grace to find my iPhone activated, ONLY the person who set up the Apple ID can remove (see: find my iPhone Activation Lock: a mechanism of extraction of the previous owner)
  • If it's the Apple ID in Settings/iTunes & App Store just log out, then log back with the correct ID of Apple.
  • Do the same for iMessage and Facetime, if that is where the Apple ID is used.
  • If he is asked during the updating of the apps means that applications have been purchased or downloaded using this code from Apple. To resolve this issue, you must remove the application, and then buy with your Apple ID.

• How to make a good UI for the selection of the channels with DAQmx

  A lot of my Labview programming accompanied verisons them previous LabVIEW (pre Labview 7), and there are a ton of new features I am digesting (currently using Labview 8.2).

  My question is (in general), how people schedule their user interface for the selection of channels and others when using hardware DAQmx?  What I have in mind is a system compacDAQ with a number of modules.  The user would be able to choose which channels to watch.  With the help of MAX as part of this process seems counter intuative and somewhat static (yes I know you can change out there, but it feels more like something you would use for something that doesn't really change much).  I wish that all the UI within the VI.

  Programmers use the task of creating screw for this or something else?

  Thanks in advance.

  ChuckNRC,

  I tend to avoid using MAX and create all my channels/tasks using the DAQmx functions.  There are also having some DAQmx features that allow you to save/remove channels, tasks and scales to MAX.

• How can I recover my pc for the first time that I bought?

  Hello
  How can I recover my pc for the first time that I bought? because my pc is so slow... I have a compaq laptop cq61... and I want to set up the first time... How can I?  I don't have a recovery disk because when I bought it dosnt have a recovery in it disc. Please help me. Thank you

  Hello

  I'm happy to help you

  Glancing at the screen shot you posted, your looks of partition fine recovery (recovery (D).

  Save your files on an external hard drive or flash drive (depending on how many you have).

  Once that is done, disconnect all connected to your PC, but the AC adapter.

  Start the PC and the HP welcome screen, press the F11 key to start the Recovery dialog box and follow the prompts.

  It should take 15 to 30 minutes and your PC needs to be restored to its factory settings.

  Then just reinstall all programs and files that does not come with the PC.

  You will need the files or the installation of program diskettes. You cannot back up installed programs and reinstall them using a backup.

  and also how the syntax would be if he is Businessunit group then group by expression (left(account,2)

  Mean you nested groups, first group BUSINESSUNIT and then other group ACCOUNT

  If yes then the internal group based on the ACCOUNT, we could watch as below

  for-each - Group: Current - Group (); xdoxslt:Left(./Account,2)? >

  For example
